Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed July 19, 1905. Serial No. 270,434.

a citizen of the United States, residing at Rockford, in the county ofWinnebago and State of Illinois, have invented certain new and usefulImprovements in Heaters, of which the following isa speciiication.

The object of this invention is to construct a heater with a centralwater-discharge, around which is located the water-supply and adepending steam-generating pipe having its open upper end communicatingwith the lower end of the discharge-pipe.

In the accompanying drawings, Figure l is a vertical central sectionthrough. the upper portion of the heater. Fig. 2 is a transverse sectionon dotted line a a, Fig. 1.

The heater represented in the drawings comprises two shells l and 2,suitably separated. Inlet-pipes 3 are located near the` lower ends ofthe shells and communicate with the space 4 between the shells. Acentral discharge-pipe 5 has a connection with the upper end of theouter shell 1K, its lower end being open. Around` this centraldischarge-pipe is located a tube 6, having its lower end closed, and itsupper end is connected with the inner shell 2 and communicates with thespace 4 between the two shells. tions between the space 4 between theshells l and 2 and the space 8 between the tube 6 and centraldischarge-pipe 5. A pipe 9 is supported by the closed lower end of thetube 6 and has its lower end closed. The upper end of this pipe is openand extends slightly Radial pipes 7 form communicainto the lower end ofthe central dischargepipe 5. The upper end of this pipe 9 is somewhatcontracted.

The arrows on the drawings indicate the directionof the low of waterfrom the inletpipes 3 out through the central dischargepipe 5. All ofthe water escaping by way of the central pipe 5 must flow to the lowerend of the pipe before it can enter the pipe. As the heat is greaternear the lower end of the central discharge-pipe 5 than at the top ofthe heater, the water, passing up and out through the discharge-pipe,will be the hottest in the heater. By the employment of the pipe 9,extending from the tube 6, the heat will come in direct contacttherewith and convert the water therein into steam and force it up thecentral water-discharge pipe 5, thereby creating a circulation of waterthrough the heating system. I claim as my invention- In a water-heater,the combination of an outer water-space, a central tube having a closedlower end, its upper end communicating with the outer water-space at thetop of the heater, a discharge-pipe located within the tube andextending upward through the top of the heater, and a steam-generatingpipe connected with the closed lower end of,y

the tube and having its open-upper end contracted and located axiallywith relation to the lower end ofthe discharge-pi e.
